Abstract
A method of applying a protective cladding, particularly to gas-tight membranes of energy boilers involves coupling of two gas-tight membranes (2) together, and then soaking a pair of gas-tight membranes (2) coupled together at 300° C. to 800° C., favorably at around 700° C.; afterwards, the membrane (2) surface where a cladding (1) is to be applied is cleaned, a pair of gas-tight membranes (2) coupled together is mounted on a positioner and then preheated up to 80° C. to 600° C., favorably to around 300° C.-450° C., and then the cleaned and preheated surface of a pair of gas-tight membranes (2) coupled together is covered with a protective cladding (1), wherein a protective cladding is applied at a thickness of 0.1 mm to 3.00 mm, favorably around 0.6 mm, and then the entire pair of gas-tight membranes (2) coupled together with a cladding (2) is finally soaked at 300° C. to 800° C., favorably at around 700° C., and the set temperature is maintained for 10 minutes to 600 minutes, favorably for 15 minutes to 30 minutes, and finally, gas-tight membranes (2) with a cladding are uncoupled.
